电-Fenton法处理硝基苯废水的试验研究

Treatment of nitrobenzene wastewater by E-Fenton technique

以多孔石墨作为阴极,以铁板作为阳极,并向阴极不断通入空气,电解过程中生成的H2O2与阳极溶解的Fe2+形成Fenton试剂,利用Fenton试剂在电解的过程中产生的大量活性羟基OH的强氧化作用来氧化降解废水中的有机物。试验证明在电-Fenton法最佳反应条件下,硝基苯迅速降解,去除率可以达到87%以上。

An electrobath was made up of iron-anode and bored graphite-cathode,meanwhile the air blew the cathode,then H_2O_2 electrolysed from cathode and Fe^(2+) came into the Fenton reagent,which oxidate organic compound by active ·OH.The results proved that under optimal conditions for EFenton reagent the nitrobenzene was able to degrede repidly with a removal efficiency of over 87%.
